The caver.kct.kip7 helps you easily handle a smart contract that implements KIP-7 as a JavaScript object on the Klaytn blockchain platform (Klaytn).
The caver.kct.kip7 inherits caver.contract to implement the KIP-7 token contract. The caver.kct.kip7 holds the same properties of caver.contract whereas additional methods to implement extra features. This section only introduces the newly added bound methods of the caver.kct.kip7.
The abi and bytecode used in the caver.kct.kip7 were implemented using the example of openzeppelin.
Deploys the KIP-7 token contract to the Klaytn blockchain. A contract deployed using caver.kct.kip7.deploy is a fungible token that follows the KIP-7 standard.
After successful deployment, the promise will be resolved with a new KIP7 instance.
Parameters
The tokenInfo object must contain the following:
NOTE The initialSupply parameter accepts number type but if the fed value were out of the range capped by number.MAX_SAFE_INTEGER, it might cause an unexpected result or error. In this case, it is recommended to use the BigNumber type, especially for a uint256 sized numeric input value.
Return Value
PromiEvent: A promise combined event emitter, which is resolved with a new KIP7 instance. Additionally, the following events can occur:
Example
// using the promise>caver.kct.kip7.deploy({ name:'Jasmine', symbol:'JAS', decimals:18, initialSupply:'100000000000000000000',},'0x{address in hex}').then(console.log)KIP7 {... _address:'0x598367e443D8a2b644Fec69a2C12aF44BC283f23', _jsonInterface: [... { anonymous:false, inputs: [ { indexed:true, name:'owner', type:'address' }, { indexed:true, name:'spender', type:'address' }, { indexed:false, name:'value', type:'uint256' } ], name:'Approval', type:'event', signature:'0x8c5be...' } ] }// Send object as second parameter>caver.kct.kip7.deploy({ name:'Jasmine', symbol:'JAS', decimals:18, initialSupply:'100000000000000000000', }, { from:'0x{address in hex}', feeDelegation:true, feePayer:'0x{address in hex}', }).then(console.log)// using event emitter and promise>caver.kct.kip7.deploy({ name:'Jasmine', symbol:'JAS', decimals:18, initialSupply:'100000',},'0x{address in hex}').on('error',function(error) { ... }).on('transactionHash',function(transactionHash) { ... }).on('receipt',function(receipt) {console.log(receipt.contractAddress) // contains the new token contract address}).then(function(newKIP7Instance) {console.log(newKIP7Instance.options.address) // instance with the new token contract address})
caver.kct.kip7.detectInterface
caver.kct.kip7.detectInterface(contractAddress)
Returns the information of the interface implemented by the token contract. This static function will use kip7.detectInterface.
Parameters
Return Value
Promise returns an object containing the result with boolean values whether each KIP-7 interface is implemented.
Example
>caver.kct.kip7.detectInterface('0x{address in hex}').then(console.log){ IKIP7:true, IKIP7Metadata:true, IKIP7Mintable:true, IKIP7Burnable:true, IKIP7Pausable:true,}
caver.kct.kip7.create
caver.kct.kip7.create([tokenAddress])
Creates a new KIP7 instance with its bound methods and events. This function works the same as new KIP7.
NOTEcaver.kct.kip7.create is supported since caver-js v1.6.1.
// Create a KIP7 instance without a parameter>constkip7=caver.kct.kip7.create()// Create a KIP7 instance with a token address>constkip7=caver.kct.kip7.create('0x{address in hex}')

kip7.clone
kip7.clone([tokenAddress])
Clones the current KIP7 instance.
Parameters
Return Value
Example
>constkip7=newcaver.kct.kip7(address)// Clone without a parameter>constcloned=kip7.clone()// Clone with the address of the new token contract>constcloned=kip7.clone('0x{address in hex}')
kip7.detectInterface
kip7.detectInterface()

kip7.isMinter
kip7.isMinter(address)
Return true if the given account is a minter who can issue new KIP7 tokens.
Parameters
Return Value
Promise returns Boolean: true if the account is a minter.
Example

kip7.paused
kip7.paused()
Return true if the contract is paused, and false otherwise.
Parameters
None
Return Value
Promise returns Boolean: true if the contract is paused.
Set the amount of the tokens of the token owner to be spent by the spender.
Note that this method will submit a transaction from the owner to the Klaytn network, which will charge the transaction fee to the owner.
Parameters
NOTE The amount parameter accepts number type but if the fed value were out of the range capped by number.MAX_SAFE_INTEGER, it might cause an unexpected result or error. In this case, it is recommended to use the BigNumber type, especially for a uint256 sized numeric input value.
The sendParam object contains the following:
NOTEfeeDelegation, feePayer and feeRatio are supported since caver-js v1.6.1.
Return Value
Promise returns object - The receipt containing the result of the transaction execution. If you want to know about the properties inside the receipt object, see the description of getTransactionReceipt. Receipts from KIP7 instances have an 'events' attribute parsed via ABI instead of a 'logs' attribute.

kip7.transfer
kip7.transfer(recipient, amount [, sendParam])
Transfers the given amount of the token from the token owner's balance to the recipient. The token owner should execute this token transfer with its own hands. Thus, the token owner should be the sender of this transaction whose address must be given at sendParam.from or kip7.options.from. Without sendParam.from nor kip7.options.from being provided, an error would occur.
Note that sending this transaction will charge the transaction fee to the transaction sender.
Parameters

Safely transfers the given amount of the token from the token owner's balance to the recipient. The token owner should execute this token transfer with its own hands. Thus, the token owner should be the sender of this transaction whose address must be given at sendParam.from or kip7.options.from. Without sendParam.from nor kip7.options.from being provided, an error would occur.
If the recipient was a contract address, it should implement IKIP7Receiver.onKIP7Received. Otherwise, the transfer is reverted.
Note that sending this transaction will charge the transaction fee to the transaction sender.

kip7.mint
kip7.mint(account, amount [, sendParam])
Creates the amount of token and issues it to the account, increasing the total supply of token.
Note that this method will submit a transaction to the Klaytn network, which will charge the transaction fee to the sender.
Parameters
NOTE The amount parameter accepts number type but if the fed value were out of the range capped by number.MAX_SAFE_INTEGER, it might cause an unexpected result or error. In this case, it is recommended to use the BigNumber type, especially for a uint256 sized numeric input value.
NOTE If sendParam.from or kip7.options.from were given, it should be a minter with MinterRole.
Return Value
Promise returns object - The receipt containing the result of the transaction execution. If you want to know about the properties inside the receipt object, see the description of getTransactionReceipt. Receipts from KIP7 instances have an 'events' attribute parsed via ABI instead of a 'logs' attribute.

kip7.addMinter
kip7.addMinter(account [, sendParam])
Adds an account as a minter, who are permitted to mint tokens.
Note that this method will submit a transaction to the Klaytn network, which will charge the transaction fee to the sender.
Parameters
NOTE If sendParam.from or kip7.options.from were given, it should be a minter.
Return Value
Promise returns object - The receipt containing the result of the transaction execution.

kip7.renounceMinter
kip7.renounceMinter([sendParam])
Renounces the right to mint tokens. Only a minter address can renounce the minting right.
Note that this method will submit a transaction to the Klaytn network, which will charge the transaction fee to the sender.
Parameters
NOTE If sendParam.from or kip7.options.from were given, it should be a minter with MinterRole.
Return Value
Promise returns object - The receipt containing the result of the transaction execution. If you want to know about the properties inside the receipt object, see the description of getTransactionReceipt.
